What is strange is that only some of these warnings are shown as
new, but not all. For example it shows
>> drivers/spi/spi-fsl-spi.c:93:44: sparse: got void [noderef] __iomem
*reg_base
as new, but not the following one:
drivers/spi/spi-fsl-spi.c:294:44: sparse: got void [noderef] __iomem
*reg_base
while both have their string changed (__iomem).
Just to be sure, I checked this file and (of course) all these
warnings are old ones, caused by a missing __iomem in the assignments:
struct fsl_spi_reg *reg_base = mspi->reg_base;
Why some are shown as new and some as old is a mystery to me.
